* remote_runner.js: fix drain call (cf.
https://github.com/caolan/async/blob/master/CHANGELOG.md#breaking-changes)
* dont wait 30 seconds after remote_runner.js returned
* timeout frontend tests after 9.5 minutes to prevent travis from silently stop them
* log when not all tests finished
* prevent killTimeout to happen after last test
* log server messages to console
* remote_runner will take some time to setup sl, so this second is not necessary
* dont write to global mocha variable
* mochas `test end` event is not called when a before/beforeEach-hooks
failed, so we should only use pass/fail/pending-hooks for logging.
also some cruft removed
* pass test in `pending`-event handler
* remove some more cruft in tests/frontend/runner.js
* frontend tests: clarify why stats.tests and total differ
* move killTimeout to pass/fail/pending instead of `test end` to guarantee that it is run
* delete killTimeout on test end to prevent misleading log message
* unused variable
* fix regex
* unlikely edge case
* ensure `allowed test duration exceeded` message is printed for the last runner
* get rid of jquery.iframe.js, currently no support for IE<9
* retry up to 3 times when pad could not be loaded
* Call the logging code in stopSauce in a callback for `browser.quit()`.
This should fix cases like

Travis received all the logs and remote_runner.js exits, but there never
is a DELETE command for webdriver.
This change only slightly modifies the bahaviour of travis/runner.sh, but:
1. speeds up the tests, because it does not install dependencies before running
them. Dependencies are already installed by .travis.yml in its "install"
section;
2. if for some reason Etherpad does not start, there is a sudden failure,
instead of launching the front end tests anyway, and then having to wait 10
minutes for them to time out;
3. it is compatible with a different way of installing etherpad dependencies
("npm ci" instead of "npm install"), whereas the previous one broke. This
will probably be introduced in a while, so this change future-proofs for it
(see #3778).
4. it is more robust, because it detects more reliably the paths, and changes
between them correctly;
Please note that the script now requires bash instead of a generic posix shell.
This may break on platforms which default to a different shell (FreeBSD, MacOS?)
